Twsbi Diamond 580 Fountain Pen - Smoke Rose Gold II KOKUYO and other ink pensAlthough relatively new to producing their own line of fountain pens, TWSBI has been in the industry for half a century, creating parts for other brands under the name Ta Shin Precision. Within a decade, their piston filled demonstrator pens have become immensely popular for their high quality, large ink capacity, and affordable price point which allows many newer fountain pen users to get their hands on a remarkable pen very early into the hobby.
